Senior blockchain engineer with 10+ years in software engineering and 7+ years specialising in EVM and multi-chain systems,across 10+ projects spanning DeFi, NFTs, DeSci, and enterprise domains. I own the full Web3 data lifecycle — smart contracts,on-chain event indexing, and backend APIs — shipping production systems built on Solidity, event-driven Node.js/TypeScript/GraphQL services, and deterministic indexing infrastructure (Subsquid, The Graph). I decompose complex architectures, take features from contract to production, and build systems that hold up under real usage.
• Most recently built Shibarium (Ethereum Layer 2) infrastructure at Shiba Inu: Chainlink CCIP cross-chain interoperability,PostgreSQL-backed Subsquid indexing, and Node.js/GraphQL backend services.

Experience
Senior Smart Contract, Web3 Backend & Indexing Engineer
Shiba Inu - Shibarium (Ethereum Layer 2 network) 2024 - 2026
• Built event-driven indexing services (TypeScript, Subsquid, PostgreSQL) synchronising on-chain state across 100K+ Shibarium L2 blocks, with deterministic event modelling, chunked block fetching, and full transaction-lifecycle handling via ethers.js RPC. • Implemented cross-chain token swap and bridging on Chainlink CCIP — ShibaSwapXChain contract, CCIP connector, and route processor enabling swaps and message passing across 5 EVM networks (Ethereum, Shibarium, Arbitrum, Base,Avalanche). • Architected the SHIFU token distribution end-to-end: Solidity contract plus Express/MongoDB service issuing merkle proofs and processing 20,000+ claims across two distribution rounds for 10,000+ wallets via ethers.js. • Designed a multi-network DEX aggregation service (Li.Fi-inspired): best-price routing, cross-chain bridge quotes, token info, and swap orchestration across 2 chains. • Developed on-chain reputation scoring (Karma Calculator, TypeScript/Node.js) across Ethereum and Shibarium — multi-network routing, event filtering, chunked block fetching, and a REST API.
Senior Software Engineer (Blockchain)
V2Soft 2021 - 2024
• Built the V2Soft 25th Anniversary NFT platform from scratch — Node.js/Express APIs, MySQL, AWS, and Solidity contracts. • Delivered the Vehicle NFT platform (ERC-721 + IPFS metadata) for on-chain vehicle lifecycle tracking, and the EarnTV Reward Engine (ERC-20 issuance, staking, NFTs, Gnosis MultiSig treasury controls). • Developed OpenTherapeutics (DeSci) smart contracts for researcher rewards, funding, and collaboration, ensuring transaction atomicity across all on-chain operations. • Mentored junior developers on Node.js, Solidity, and testing as part of the Blockchain Innovation Team.
Senior Blockchain & Backend Engineer
Self Employed / Freelance 2019 - 2021
• Designed and deployed production smart contracts for staking, rewards, vesting, and ERC-20/721 token ecosystems, delivering full stacks (contracts → APIs → indexing → infra) that reduced client engineering costs. • Led backend and blockchain development team at Humation Limited — cross-chain interoperability across Ethereum, TRON, Waves, and Stellar.
Senior Software Engineer
Harbinger Systems Pvt. Ltd. 2017 - 2019
• Built ImagineBC (privacy-focused blockchain on a private Geth network) and Certificate of Authenticity (ERC-721 artwork provenance with IPFS and React.js). • Delivered Loan Lending and Land Records DApps with 100% smart-contract test coverage via TDD, and forked the ARK blockchain to build Blockpool. • Provisioned blockchain nodes on AWS and deployed across Ganache, private networks, testnets, and mainnet.
Associate Software Engineer
AtoS India Pvt. Ltd. 2014 - 2015
• Monitored production servers and batch jobs, validated endpoints, and performed root-cause analysis to keep backend systems reliable.
